This tool trims the margins of a PDF document across all of its pages, with a live preview showing the result before you confirm — handy for removing a useless scan edge or tightening a layout. The crop is computed in your browser. No file is sent to a server during the operation.
Enter the margin to remove at the top, bottom, left and right in millimetres: the live preview shows the result before you confirm, and the crop is then applied to every page of the document.
If the margins you enter exceed the usable page area, Vellum warns you before you confirm. Check the preview to make sure no important text or image falls within the area being removed.
No, the calculation happens in your browser, without transmission to a server, and the tool is free. A password-protected PDF must be unlocked before it can be cropped.
